well i've have given my toughts on this matter earlyer, but little refresh might be good.
I personally think that it's quite useless to try comisioning Minsk and Kiev in to PLAN service. Why? First of all those ships are old...Kiev was laid down in july 1970 and minsk december 1972, Now the Soviet shipbuilding quality wasen't the best of the world and these ships weren't good desings from the start. They tended to pitch at the fore in heavy seas. Also, as it been mentioned, the machinery was far from succesfull, all 7 soviet carriers have undergone major fires and all due the same reasons: the unrealible pressure fired steam plants. The ships where in bad shape when they where sold to china and given the time that they are being whitout major overhaul, it's desperate to try and make them operational again. It propaply could be done, in theory, but in practice is just waste of valuable resources...they are just too old to rock'n roll...
Seccondly the ships overall desing features are major handycap. The ships where orginally desinged to be updated Moskva class whit improved helicopter capapility and the ASuW weapon suite that had to be deleted from the Moskvas during the desing date. The V/STOL concept game along only after the Yakolev desing burey succesfully demostrated the Yak-36 prototype to the naval chiefs...The ships where also sort of a compromize for real carriers, the Soviet navy was still recovering from Hrurzevs era and wasen't still ready for real carriers. But now to china. If by some miracle the Kiev and Minsk could be overhauled to the point that they are again usefull, what exactly could china do whit them? China doesen't posses any V/STOL technology and thats leaves the ships only whit helicopters. for my obinion these ships are too big and expensive to serve as a helicopter carrier. The same ammount of money that is needed to refit these ships could easily buy a small Chahri Narubet-style helicopter carrier.
Then there's always the Gorshkov conversion for India...why shouldn't China go ahead whit these ships in similar way...clear up the deck for Ski-jump??
Well Gorshkov was orginally blanned for that kind of conversion, thats why there's no reloads for the SS-N-12 and no SA-N-3 launchers...the Kiev and Minsk are another deal. I've never seen the blueprints of these ships but if you remove so much from these ships foresections it propaply changes dramatically the ships overall balance. Also the hangar base expesially in kiev is way smaller than in Gorshkov, so in that case also the already limited airwing of the Groshkov conversion would be even smaller. And the airwing itself is a proplem. China doesen't have any suitable jets to operate from the carrier. Chinese aircraft manufacturing isen't in the phase that it could start desing carrierbrone aircrafts even from existing models, in this case the J-10. It would just take too long to get the J-10s naval version to work and then the already ageing ships would be totaly overaged. The Su-27/33/J-11 is just too big and the MiG-29 isen't part of the chinese airfleet..
So basicly, in my obinion trying to get these ships operational is just too big effort. The attenion and recources should be focused on the Varyag, wich is far more ideal phase to become the first fixedwing aviation asset of the PLAN.
Now this was my obinion, feel free to comment and give your own wievs...
